Position- Time Graph
The slope of a position time graph is velocity.
When the slope is positive, it indicates that the object is moving forward
When the slope is negative, it indicates that the object is moving backwards.
When the slope is zero, it indicates that the object is at rest.
When the line crosses the x axis it means that the object has moved behind the point where it originally started. This did not happen in the graph because we never moved behind the motion detector.
Velocity- Time Graph:
The slope of a velocity-time graph is acceleration.
When the slope is positive, it indicates that the object is accelerating forward.
When the slope is negative, it indicates that the object is decelerating backwards.
When slope is zero, the object is accelerating constantly.
When the line crosses the x axis, it means that the velocity is zero. This happened in the graph because there were times when the person was not moving.
